Exports climbed 0.6% to $192.8 billion, led by increased sales of U.S.-made machinery, aircraft and medical equipment. Imports also rose 0.6% to $231.6 billion, reflecting a 9% jump in imports of petroleum. Imports of food and machinery also rose.

The trade deficit is the difference between imports and exports. A higher trade deficit acts as a drag on economic growth because it means U.S. companies are making less overseas then their foreign competitors are earning in U.S. sales.

In 2013, the trade deficit dropped 11.2% to $474.9 billion, providing a small boost to overall growth. Economists believe that trade will contribute to growth again this year but only by a modest amount. They are forecasting that U.S. exports will keep rising, but that this will be offset somewhat by gains in imports as a stronger U.S. and higher consumer spending attracts more foreign goods.

In the October-December quarter, the economy grew at an annual rate of 2.4% and a full percentage point of that growth came from a shrinking trade deficit. For the whole year, the falling trade deficit contributed a smaller 0.1 percentage point to growth.

One bright spot for trade: America's increased energy production is expected to continue. A domestic energy boom has boosted exports and reduced America's dependence on foreign oil. U.S. petroleum exports rose to an all-time high of $137.2 billion last year, up 11% from 2012. Imports were down 10.9% to $369.4 billion as domestic production took the place of the need for some imports.

For January, petroleum imports jumped 9% to $31.7 billion, reflecting an increased volume of shipments. The average price for a barrel of crude oil fell to $90.21, the lowest level since February 2011. America's energy exports dropped 8.4% to $12.4 billion.

As usual, the highest country trade imbalance was with China, a deficit of $27.8 billion, up 13.5% from December.

The deficit with the 28-nation European Union fell 22.2% in January to $8.9 billion as U.S. exports to that region increased while imports from Europe to the United States declined.

The United States recorded another record annual trade deficit with China in 2013 and the expectation is that the deficit will rise further in 2014. That has led to increased pressure on the Obama administration and Congress to take a tougher line on what critics see as unfair trade practices that China is using to gain trade advantages.

The chief culprit, the critics say, is China's manipulation of its currency to keep it undervalued against the U.S. dollar. That makes Chinese goods cheaper in the United States and America products more expensive in China.
